Both AT&T and Verizon confirmed that their customers may be currently experiencing outages.

"A power and connectivity issue is causing a service interruption in parts of Napa, Sonoma and Mendocino Counties," Verizon Wireless Pacific market public relations manager Heidi Flato said. "Our engineers are aware of this issue and are working with our vendor partners to resolve this issue quickly."

A media relations director from AT&T confirmed that some wireless customers in Humboldt County may also be experiencing "issues with their wireless services."

Late Monday afternoon, Santa Rosa Police announced that Verizon will be providing free wireless hotspots to help locals without cell access. On Tuesday, AT&T sent Sat COLTs, a mobile cell site that links users to the network via satellite, to Santa Rosa, Willits and the Napa Town and Country Fairgrounds. Charging stations have also been sent to Napa Valley College, Sonoma County Fairgrounds and Santa Rosa Veterans Memorial Building.

Locals whose cell service is down can still use wifi to send messages or make calls (here's an FAQ on how to do that). Officials have asked that people only call 911 if they see unattended flames, as emergency services are currently overwhelmed.
